What they say
"Man, I just finished programming a little game with Alan, and let me tell you ALAN RULES!! It's so simple, *I* can program with it."
Rob Anderson
"I think it's the best IF language I've ever seen - and I *am* a programmer."
Andrew Heale
"Well, it was very easy to learn and it's easy to do stuff in it."
Mikko Vuorinen
"All those weirdly arranged parentheses, and semi-colons and strange curlicues hanging out in the middle of blank lines. Impossible. But when I looked at Alan I saw the light or, at least, English."
Eric Mayer
"[the game] does not represent the real capabilities of the Alan Language but does demonstrate Alan's amazing ability to allow someone who has never done an iota of computer programming of any kind to produce SOMETHING within a few weeks!"
Eric Mayer (on his game HeBGB Horrors)
"If I was to write a new text adventure I wouldn't bother with any other authoring system. Alan is just that much easier."
